Abstract

In our work, we introduce BATTLE, Bonded Adversarial TournamenT with Logarithmic Escalation, a tournament-style protocol that solves multiparty disputes with simultaneous assertions such that (i) bounds honest asserter capital requirements to a constant minimum initial capital and (ii) resolves any number $C$ of concurrent challenges in $\mathcal{O}(\log C)$ dispute rounds, by reinvesting dispute rewards to fund subsequent rounds (progressive buy-ins) (iii) can be realized on a stateful (Quasi)Turing-complete smart-contract enabled blockchain. BATTLE solves a set of conflicting assertions by creating a tournament with two phases: (1) a bracket among competing asserters with one dispute per party per round, and (2) a challenger phase against the winning assertion where the asserter engages in increasing number of simultaneous disputes each round.
